1. Excel Learning - Basic Application (WPS)

1. Excel Practical Skills

1. Copy the cell as a picture

• Select the target area, right-click, and select "Export cells as pictures"
  

• Setting the following options may not require WPS membership:
  

• Click "Open Image" to see the generated image:
  
  ## 2.

2. Change the number in "Yuan" to "Ten Thousand" in unit

• Enter 10000 in any blank cell, select the cell range to be converted, right-click, click "Paste Special", select "Value", and then select "Divide", and confirm.
  
  

3. Enter the same data in multiple cells

• Select multiple cells, enter the required content, and press Ctrl+Enter to enter in batches.

4. How to hide cell content

• Method 1: Set the cell format to three semicolons ";;;". (The content cannot be seen in the cell, but can be seen in the edit box)
• Method 2: "Format Cells" → "Protect" → check "Hide". (The content cannot be seen in the cell, but can be seen in the edit box)
• Method 3: Protect the worksheet. (I can't see the content either inside the cell or in the edit box)

5. Use the Excel status bar skillfully

• Right-click on the status bar to select mean, count, count value (only cells containing values), maximum value, minimum value, and summation. When a cell is selected in the worksheet, a corresponding prompt will appear in the status bar.
  

6. Quick Paste

• After copying the contents of the selected cell, select the target cell, and press the Enter key directly to achieve quick paste. (Only the first carriage return is valid, and one or more copied or copied cells can be selected)
  

7. Quick zoom display ratio

• Hold down the Ctrl key and scroll the mouse wheel.

8. Two ways to enter the formula

• Method 1: "=" + content. (regular input)
• Method 2: Instead of "=", directly add "+" or "-" (the meaning of the sign) before the formula, and "=" will be added in front by default. (Example: -27 +14 +B2 -B1)

9. Hide Subtotal Rating Button

• Press Ctrl+8 when hiding, and press Ctrl+8 when redisplaying.

2. Learning common formula functions

1. Definition and difference between formula and function

• A formula is an equation that starts with "=", followed by data and operators, and returns a value.
• A function is a predefined function inside Excel, which starts with "=", calculates according to specific rules, and gets a return value.
• Similarities between formulas and functions:
  • 1. All start with "=".
  • 2. Both get the return value.
• Differences between formulas and functions:
  • 1. Functions can be part of formulas, but formulas don't always need to contain functions. (the scope of the formula is larger)
  • 2. Functions have unique function names, and each function has specific functions and uses, and is calculated strictly according to specific rules.

2. Operators

1. Classes of operators

1. arithmetic operator
   

2. comparison operator
   

3. quote operator
   

4. text operator
   

2. Operator precedence

• When there are multiple operators in a formula, Excel will perform operations according to the precedence of the operators. If they are operators at the same level, they will be operated in order from left to right.
  
• If you want to change the precedence of an operator, you can use parentheses "()". For example, =2-1*3 returns -1, and =(2-1)*3 returns 3.

3. Relative references, absolute references and mixed references

1. Relative references

• The cell reference will change with the position of the cell where the formula is located, which is called a relative reference. For example B1, B2, etc.
  

2. Absolute references

• Contrary to relative references, cell references will not change with the position of the cell where the formula is located, and are called absolute references. For example $B$1, $B$2, etc. (You can select the cell symbol and press F4 to lock the cell and set it as an absolute reference)
  

3. Mixed references

• Only one of row or column is fixed.
• A$1: The column is changing, but the row remains unchanged.
• $A1: The column is unchanged, but the row is changing.
  

4. IF function

1. Grammar

IF (judgment condition, the value obtained when it is established, and the value obtained when it is not established)

2. Examples

1. Judging whether the grades are passing
   
   
2. Bonus Schedule

5. IFERROR function

• Function for handling errors.

1. Grammar

IFERROR(expression, errorhandling)

2. Examples

1. Procurement schedule
   
   
2. Credit Task Assessment Form
   
   

6. AND function

1. Grammar

AND (judgment condition 1, judgment condition 2, ..., judgment condition 30)

can contain up to 30 conditions.
It is usually used as the condition of the IF function, and the return value is a Boolean value, that is, TRUE or FALSE.

2. Examples

1. Appraisal and assessment
   
   
2. Bonus Schedule
   
   

7. OR function

1. Grammar

Or (judgment condition 1, judgment condition 2, ..., judgment condition 255)

can set 255 judgment conditions in total.
As long as a judgment condition is true, it will return TRUE.

2. Examples

1. Appraisal and assessment
   
   
2. result
